in the roll diameter due to the roll picking up lint or other matter. These rolls frequently pick up lint from the drawn-in yarn or sliver, which increases the roll diameter,

19 and generally in spots, the present invention aiming to provide means accordingly to meet this situation. v

A further object of the invention is to provide a novel means whereby a clearer roll may be detachably mounted between the drawing-in and intermediate sets of rolls in a spinning machine of the long draught type.

A further object of the invention is to so mount the clearer roll as to permit limited 99 forward and rearward movementvand also vertical relative to the stationary sets of rolls.

A still further object of the invention is to balance the supporting means so that the clearer rolls will be allowed free movement and thus increase the efliciency of their operation. Further objects and advantages will become apparent as the description proceeds, reference being had to the accompanying drawing in which;

Figure 1 is a perspective view of the supporting clip; 7

Figure 2 is a fragmentary perspective view of the clearer roll;

Figure 3 is an elevation of the clasp and roll in operative assembly showing in dotted lines the action of the clip upon movement of the roll; and

. Figure 4 is a fragmentary plan assembly showing the roll and clip in operative position.

In proceeding in accordance with the present invention, a clearer roll 1 is shown which .is mounted as shown in Figure 4 below and between the drawing in rolls A and the intermediate rolls B of a spinning machine of the long draught structure. The clearer roll 1 has portions of its surface cut away to form .a cylindrical neck or axle, 2. These reduced portions or necks 2 occur'at points which are p in registry with the portionof the stationary rolls-which are not used'in the attenuation of the yarn. 1

I For the purpose of supporting the clearer 1 rolls inthe desired relation to the rolls A and B,l-spring clips'3 are provided. These clips consist of a U-shaped saddle 4 carrying a weight 5 on oneend andhaving a shelf like 6 extension on the other, the latter having an upturned lip 7 at its'free end. The saddle do or bight of the U is of substantially the same 'widthas, the space between the adjacent.

drawingin rolls AA and conformably seats upon the part A of the shaft of the rolls so N that no movement axially of its support may be had when the clip is in position. The extension 6'serves as a bearing surface for the neck 2 of the clearer roll. and by virtue'of itsupturned end or lip 7 allows a certain free- V, dom ofmotion to the clearer roll 1 backward and forward with relation tothe rolls A and B; The weight 5 is securedto the body of the clip by the insertion of screw head 8 in the slot 9 which latter has its upper end enlarged to a greater diameter than that of 7% the screw head 8, so that the clip .may be removed, and applied without -complete .removal of the screw. 1 e

l A lubricant passage 10 is provided tonable lubricant to be supplied therethrough to' r-educethe frictionalresistance between the shaft of rolls A and the clips 3. y

Inoperation, the-clips3 are placed over the shaft carrying the drawing-in rolls so I, as "to be supported thereby and the clearer roll 1 is' positioned so that its surface contacts rolls A and B and its neck portions engage the shelves 6 of the clips 3. When the machine is running the clearer roll may accordingly move forward or backward or V61 tically due to the presence of lint or due'to the diflerence in'speed 'of rolls A and B, thereby affording'unifor ity of its action.

'Having-thus described my invention what I claim as new and desire to secure by Letters Patent-isz J y 'l fln'cor'nbination with the drawing-in and intermediate rolls of a spinning machine, a clearer rollunderlying and contacting both the drawing-in and intermediate rolls, said clearer roll having a portion of greatly reduced diameter intermediate its ends and in registry with the unused portions of the drawing-in roll, a spring bearing clip carried by the axle of the drawing-in roll and having a shelf like projection for engagement with the axle of said clearer roll to support the same, said shelf having an upturned outer end which acts in conjunction with the body 7 and a clip member having a part mounted on the shaft of and in the space between the drawing-in rolls so, as to be solely supported by and for swinging movements on said shaft, a seat carried by said member and of greater length than and receiving said-reduced part of the clearer roll to support the latter for movement lengthwise of the seat, and counterbalancing means connected to the member.

3. In combination with a shaft having spaced drawingein rolls, and the intermediate rolls of a spinningmachine, a clearer roll underlying and contacting the drawing-in and intermediate rolls and having a reduced part and a clip member having a part mounted on the shaft of and in the space between the drawing-in rolls for swinging movements on said shaft, means for mounting the reduced part of the clearer roll on the member for bodily movement lengthwise of the last named means, and counterbalancing means connected to the member.

4. In combination with a shaft having spaced drawing-in rolls, and the intermediate rolls of a spinning machine, a clearer roll underlying and contacting the drawing-in and intermediate rolls and having a reduced part and a strip-like member having a part mounted on the shaft of and in the space between the drawing-in rolls so as to be solely supported by and for swinging movements on said shaft, aseat carried by said member and receiving said reduced part of the clearer roll to support same, for limited bodily movement lengthwise of the, seat, and counterbalancing means connected to the member.

5. In combination with a shaft having drawing-in rolls and the intermediate rolls of a spinning machine, a spring clip of substantially U-shape having its bight received on the top of the shaft of the drawing-in rolls, a clearer roll underlying and contacting the drawing-in and intermediate rolls, holding means carried by and extending outwardly from one end of the clip for supporting the clearer roll for bodily movement lengthwise of the holding means, and counterbalancing means connected to the outer face of the opposite end of the clip.

In testimony whereof I have signed my name to this specification.

JAMES A. ANDREWS.
